I don't know what to do with these damn things. The hub is a Formula/IRO/Nashbar/Rebranded-by-everyone track hub and I've been riding it for a long time in all sorts of weather. When I took the wheel off I noticed the bearings were really gritty so I wanted to replace them. I've been using this method: http://projekto-b.blogspot.com/2008/...-bearings.html which is basically just take off locknuts, cones, etc, put a block of wood on top of the axle and whack the wood with the hammer. No dice. I'm whacking it HARD and the bearings won't budge. I tried both sides. Any ideas? Is there a better way to do this? If I take it to my LBS will they have a tool for it? Is it possible to hit too hard and damage the hub or should I just find a bigger hammer?
